Diascia plant named &#39;diasupa&#39;

ABSTRACT

A new  Diascia  plant particularly distinguished by its light pink flowers, which produces no seeds, and has a growing habit that is first upright and later spreading and hanging.

LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED

Diascia barberae

VARIETAL DENOMINATION

‘Diasupa’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new distinct cultivar of Diascia, botanically known as Diascia barberae.

The new cultivar is propagated from cuttings resulting from the cross of ‘Diastara’ and ‘Diastis.’ ‘Diastara’ is a light pink flowering Diascia. ‘Diastara’ is commercially available and is known by the synonym ‘Flying Colors Appleblossom.’ ‘Diastis’ is a coral flowering Diascia. ‘Diastis’ is commercially available and is known by the synonym ‘Flying Colors Coral.’ ‘Diastara’ is patented as U.S. Plant Pat. No. 14,782. ‘Diastis’ is patented as U.S. Plant Pat. No. 13,950

As a result of this cross the present cultivar was created in 2002 in Enkhuizen, Netherlands and has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands and Sarrians, France over a three-year period. It has been found to retain its distinctive characteristics through successive propagations. The new variety is stable and reproduces true to type in successive generations of asexual reproduction.

This new Diascia plant is an annual in most climatical zones in the US, only in zones 7, 8, 9 and 10 it is a perennial plant.

DESCRIPTION OF THE DRAWING

This new Diascia plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color shown being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new Diascia. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 10 week old plants, cultured in 10.5 containers, blossomed under natural light in a greenhouse.

Color readings were taken in the greenhouse under ambient light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.
